Shall I tell you where the dead are?
Shall I tell you where the dead are?
You won't find them in the sky
Their faces don't grace clouds,
or rest in a person's eye
Shall I tell you where the dead are?
You won't find them on the street
If you missed them the first time,
then there's no chance they'll repeat
Shall I tell you where the dead are?
You won't find them on a wall
A picture is but a picture,
and that just won't do at all
Shall I tell you where the dead are?
You won't find them in a book
Better catch them while they're living
Better have yourself a look
Shall I tell you where the dead are?
You won't find them in a voice
They've moved on to different pastures,
but not one is there by choice
Shall I tell you where the dead are?
Very well, you'll get your way
The dead rest in the ground,
and it's there they'll always stay

Nanotechnology
(sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with structures sized between 1 to 100 nanometre in at least one dimension, and involves developing materials or devices possessing at least one dimension within that size. Quantum mechanical effects are very important at this scale, which is in the quantum realm.
Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale.
There is much debate on the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials,[1] and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.
